I am using the latest version of emacs 24 from the repository, I have just updated and rebuilt today and I am seeing some strange and rather annoying problems. I will try to explain what I am seeing, let me know if it is to incoherent to make sense, I can lok into creating a video or something. My problem essential is that I seem to lose the cursor upon startup (as it becoming invisible, I still have a welldefined point where charactyers are inserted, but I cannot see the cursor itself). I have a rather involved .emacs, built up over many years, using a multiframe setup. Basically, during startup I load and configure a bunch of stuff and open a couple of predefined frames which are closed again, leaving just one frame open. When .emacs evaluation is finshed and I look at my open frame, it has no cursor. Typing C-l doesn't help, the cursor remains invisible. If I then switch to one of my other frames, the cursor reappears in the initial frame, but if I continue to de-iconify other frames, they too has an invisble cursor. Switching between now no longer helps, so I need to delete those frames and recreate them. Once they have a visible cursor, it seems to stay visible. Starting up with -q (or --daemon) seems to avert the issue, so I do not have any easy way of reproducing it. My theory is that something topples due to these frames being creating during initialization (.emacs evaluation) and C-l for some reason either doesn't work as reliably as it once did or something optimizes away some redisplay that I need. I am unsure exactly when this behaviour has started, sometime last year (2013). At first I thought it was just related to me running on a rather old RedHat Linux server installation, but now all my installations on both Linux and Mac OSX are affected. I do not use gnome and compile with the lucid toolkit. Does this ring a bell with anyone? I think I shall be able to rewrite my startup to code around the issue (at least if the time of creating the frames somehow is involved) but I wanted to raise the issue before just burying it. I know the above description is in itself not usefull for debugging the problem, let me know if there is any other information I can provide or if you want to pursue it at all. ------------------------+----------------------------------------------------- Christian Lynbech | christian #\@ defun #\. dk ------------------------+----------------------------------------------------- Hit the philistines three times over the head with the Elisp reference manual. - petonic@hal.com (Michael A.
